I think we’re in a Sakana matzav already (see below) and only Gedolim can advise, perhaps allowing and enabling by organizing and providing the “Who What When and Where” for older singles to meet on their own, or semi supervised, with the same interest and commitment as when planning Siumei Shas. It can be done.
I see some frustrated older single girls going towards what they think are greener pastures, and we dont want that. Its heartbreaking for all.
